What are the tyres made of and what is the manufacturing process?
Section 1: squeeze outCompound feed extrusion die, extrusion and semi-finished rubber: different parts of the tread, sidewall and bead triangle / strip.
Section two: RollingThe raw material cord passes through the calender, and both sides of the cord are hung with a thin layer of glue, and the final product is called cord". The main material cord is nylon and polyester two kinds.
Process two: plastic parts preparation processThe plastic parts preparation process consists of 6 main sections. In this process, all semi-finished rubber components that make up the tire will be prepared, some of which are initially assembled.
Refining process is the process of mixing carbon black, natural / synthetic rubber, oil, additives, accelerators and other raw materials, processing in the mixer, and producing the "glue". All raw materials must be tested before entering the mixer and can be used after being released. The weight of each mixer is about 250 kilograms. Each rubber component used in the tire is of a specific property. The composition of the rubber depends on the performance requirements of the tire. At the same time, the change of the composition of the rubber depends on the needs of the manufacturers and the market. These requirements mainly come from traction, driving performance, road conditions and the requirements of the tires themselves. All glue shall be tested before entering the next process - Preparation of plastic parts, and shall be released before proceeding to the next process.
